Bruce,
Howa makes some excellent rifles, and they are popular all over the world. They are known to be accurate right out of the box. I can see no reason why the .375 will be different. They are very competitively priced. I have recently only purchased my first Howa, but in .243 Win. and would not have done so, if it was not for the numerous excellent feedback I got from Howa owners. If you are looking for a good .375, you could have a look at the CZ 550. Evertime I shoot it , the accuracy only impresses me more and more.
Best Regards
